i was driving down the road today playing around, and i noticed whenever i turn my over drive off, that it doesnt stay off the light starts blinking, and the car starts jumping rpms, like its going on and off. any ideas what the prob could be?

 

Hopefully someone can give some insight, because my O/D switch doesn't even work. I think its stuck in O/D all the time...

There is a procedure for reading codes stored in the Transmission Control Module (TCM). This can be found in a Haynes Manual, FSM or in our very own 4th Gen FAQ.

Give that a try and come back with the results.

 

do a search on checking ecu codes
then the number of blinks should correspond to a problem u are having

 

The same thing happened to me. When I disassembled the shifter **** I discovered that the plastic material is broken in the area of the overdrive button. It looks like this does not allow the switch to stay on. If you find this is your problem then...

Try to repair or replace the shifter ****. In my experience there are no aftermarket replacements that will look good (but everything is a matter of taste). You could try to get a shift **** from a junkyard or just buy it new.

Other solution is to retain the damaged shifter **** and relocate the switch to a different location with an electrical switch. A sugestion could be to obtain a oem switch for other function (such as hazard lights, and defroster) and make it work for the overdrive function, then install it in one of the spare spaces that are always available in the dash.

Other possible solution could be to replace the **** with a better looking aftermarket **** with no OD button and relocate the button as suggested above.

Hope this helps.
